  • Patent number: 10667748
    Abstract: A system and method configured to control pressure during enhanced cough flow of a subject are provided. A pressure regulator is operated such that during an individual exhalation of the subject, the pressure regulator is toggled between a first mode in which a subject interface is closed such that substantially no gas is communicated with the airway of the subject there through and a second mode in which the subject interface is opened to cause a series of exsufflation events for the individual exhalation of the subject. The pressure relief valve is associated with the subject interface and configured to open and release gas out of the subject interface, responsive to pressure within the subject interface exceeding a predetermined threshold value so as to maintain the pressure within the subject interface within a predetermined pressure range during the enhanced cough flow.

    Abstract: An intelligent bionic expectoration system and a three-way device thereof. The intelligent bionic expectoration system includes a negative pressure suction module, a central processing module, a patient interface unit and a respiratory muscle synchronous motion module. The central processing module controls two valves to open or close, closing one valve while opening another valve, and controls the respiratory muscle synchronous motion module. The patient interface unit is connected to the positive pressure ventilation module and the negative pressure suction module, allowing positive or negative pressure airflow to flow by, depending on which valve is open, so as to allow airflow to flow in or out of the lung. The respiratory muscle synchronous motion module can employ nerve stimulation and mechanical pushing, and acts synchronously as the airflow moves, thereby simulating human coughing and achieves bionic expectoration.

    Abstract: An oxygen-supplying respirator requiring no electric power is provided. The oxygen-supplying respirator, which is driven not by electricity but by the oxygen supply pressure at an external oxygen supply end, includes an oxygen supply valve unit in communication with the oxygen supply end so as to turn on and off oxygen output therefrom. An inhalation/exhalation time setting valve unit is in communication between the oxygen supply valve unit and the oxygen supply end, receives the oxygen continuously supplied from the oxygen supply end, and outputs oxygen to the oxygen supply valve unit intermittently. Thus, the oxygen supply valve unit is driven to turn on the oxygen supply end intermittently and thereby enable intermittent oxygen output. The respirator can supply oxygen to a patient where there is no electricity.

  • Patent number: 8826905
    Abstract: A disposable breathing circuit is adapted to be connected between a disposable face mask and a vacuum source for delivering fresh gas to the face mask and for scavenging waste gas exhaled from the face mask. The breathing circuit includes a fresh gas supply tube, a flexible flow-through exhalation bag, an exhalation tube disposed between the face mask and an entry port of the exhalation bag, and a scavenging tube disposed between an exit or of the exhalation bag and the vacuum source. The exhalation tube includes a one-way valve to prevent re-breathing.

  • Publication number: 20140190484
    Abstract: A flexible transparent multiple use face mask that encloses a user's face allowing the user's airway to be ventilated that includes a transparent flexible airway mask that encloses and ventilates a user's airway, an airway adaptor that directs a quantity of ventilation to the transparent flexible airway mask, a manual resuscitation bag valve that receives the airway adaptor and controls the quantity of ventilation directed to the transparent flexible airway mask and a manual resuscitation bag that produces the quantity of ventilation transmitted through the airway adaptor to the transparent flexible airway mask. The multiple-use airway mask may also be turned inside-out and be utilized in combination with an endotracheal tube or a tracheotomy tube and also includes an optional attachment strap to prevent losing the transparent flexible airway mask as an added safety measure to keep the mask and bag connected.

  • Patent number: 8770194
    Abstract: A gas assisted re-breathing device is provided for life support of individuals venturing into harsh environments, particularly the underwater environment, which results in reduced work of breathing. In the pressurized gas assisted re-breathing device, pressurized gas, actuated by the breathing pressure local to the mouthpiece, acts to move a flexible gas storage container on behalf of the individual and a loop seal valve is forcibly shut during assisted breathing, which seals the assisted breathing loop to prevent premature venting of breathing gas to the surrounding environment, unless the assisted breathing loop is full, whereupon the loop seal valve opens to allow excess breathing gas to escape into the surrounding environment through forcible exhalation by the individual through one or more conventional one way valves that prevent backflow from the surrounding environment back into the loop.

  • Patent number: 8770192
    Abstract: A system for preventing the delivery of hypoxic gases during respiratory support of a patient includes a breathing circuit. An input device is operable by a clinician to input at least one ventilator parameter value. A fresh gas manifold is pneumatically connected to the breathing circuit and the fresh gas manifold is configured to provide at least oxygen and balanced gas to the breathing circuit. A digital signal processor is communicatively connected to the input device and the fresh gas manifold. The digital signal processor receives the input at least one ventilation parameter value, calculate a predicted oxygen concentration, and compares the predicted oxygen concentration to a predetermined minimal oxygen required threshold of the patient. A method of preventing the delivery of hypoxic gases to a patient includes providing ventilatory support to the patient through a breathing circuit. A digital signal processor receives a ventilation parameter value from an input device.

  • Publication number: 20140107517
    Abstract: A nasal cannula allows insertion of an upper endoscopy probe, a transesophageal echo probe for exams, or the like. Currently, a nasal cannula is used to measure expired carbon dioxide and deliver oxygen to sedated patients undergoing these procedures. Use of a face mask, such as a non-rebreathing face mask, during these procedures allows increased delivery of oxygen in patients with compromised respiratory function. A side port can be cut into the non-rebreathing face mask to allow insertion of the probes into patient's mouths while allowing delivery of a higher oxygen concentration. The facemask has the ability to easily separate from the nasal cannula, providing for continued use of the nasal cannula during, for example, a recovery period from sedation.
